Properties, applications and usesof Technical Textiles

DEFINITTIONS

Some years ago. Old definition“Technical textiles are considered all fabrics that can not be addressed within the traditional sectors of clothing, home and decoration”

Now“Materials designed for specific applications requiring concrete and demanding properties (mechanical resistance, tenacity, insulation, thermal resistance, acids, UV, IR….)”

specialisation

APPLICATIONS

• Mechanical functions

• Exchange functions

• Functionalities for living beings

• Protective functions

Mechanical functions

• Mechanical resistance

• Reinforcement of materials

• Elasticity

• Tenacity

Exchange functions

• Filtration

• Insulation and conductivity

• Drainage

• Impermeability

• Absorption

Impermeability Breathability fabrics

Functionalities for living beings

• Antibacteria

• Antidustmites

• Biocompatibility (hypoallergenic textiles)

• Biodegradability / bioresorption

Antibacteria and dustmitesfinishing bed

aureus staphylococcus

Protective functions

• Thermal

• Fire

• Mechanical

• Chemicals

• Impermeable - Breathable

• Antistatic

• Particles antirelease

• Electrical insulation,

• IR and UV rays,

• NBC (Nuclear, biological and chemical)

• High visibility

• Electromagnetic fields …

Functional or Functionalized Textiles = Textile + something for adding value

By chemical or physical modifications to create new functions such as:

• Antidustmites (Microcapsules)

• Adaptative or smart functions (Plasma)

• Compatibility with environment or other materials (Natural Fibers)

Dissemination of the Technical TextileKnowledge implies a multidisciplinary approach

For all future engineers:textile has to be used as a material comparatively with iron, wood, glass, ceramics, plastics...

For all future textile technicians, engineers or managers:textile has to be used as a multifunctional material having highlevel of physical, mechanical, thermal, chemical properties…
